Dark factory operator; built and runs the 3-person Level 5 engineering team strongdm
Dark Factories

Justin McCarthy

Co-Founder and CTO of StrongDM and the most prominent real-world example of a dark factory operator. His 3-person engineering team ships production software with zero human code writing or review, using the Attractor agent, markdown specification files, and external scenario testing.

Justin McCarthy is the co-founder and CTO of StrongDM and the closest thing the industry has to a confirmed, public dark factory operator. His team represents Dan Shapiro’s Level 5 in practice, not theory.

The StrongDM Factory

Under McCarthy’s direction, StrongDM’s engineering team:

  • Writes specification files in markdown
  • Runs the Attractor agent to implement them
  • Tests via external scenarios the agent never sees during development
  • Operates digital twin environments for external service simulation
  • Ships to production without any human reviewing the code

The team eliminated sprints, standups, Jira boards, and all traditional coordination layer structures — because those structures exist to coordinate humans, and their humans aren’t writing code.

Key Quotes

From StrongDM’s public materials: “Code must not be written by humans. Code must not be even reviewed by humans.”

Why This Matters

McCarthy’s approach proves the dark factory isn’t theoretical. It’s running in production, shipping a significant Rust/Go codebase, and doing it with 3 people where traditional teams might employ 15–20.

The compute budget (~$1,000/engineer/day) is the new headcount budget. The organizational question McCarthy has answered is: what does a software company look like when implementation is commoditized?
